World’s largest carbon removal plant

Carbon Casting is a new approach to carbon removal that leverages readily available biomass, such as residues from timber and farming operations. We dry and compress it into dense carbon blocks protected by an environmentally-safe, impermeable barrier, and then store these blocks in underground sites with state-of-the-art monitoring. Carbon Casting preserves nearly all the carbon captured in the biomass and consumes very little energy in the process.

Combining photosynthesis with practical engineering, Graphyte’s Carbon Casting technology provides an immediate pathway for billions of tons of low-cost, durable carbon removal.

What is Biochar?

Biochar is a carbon removal method where organic materials like wood or crop waste are heated in a low-oxygen environment to create a stable form of carbon called biochar. This process, known as pyrolysis, turns the carbon into a solid that can be buried in soil. Once in the soil, biochar can trap carbon for hundreds to thousands of years, helping to reduce the amount of CO2 in the atmosphere.

Beyond carbon removal, the biochar process also addresses waste management and enhances soil fertility, leading to improved agricultural productivity.

The Intergovernmental Panel on Climate Change (IPCC) has recognised biochar as a viable carbon removal method. Similarly, the European Commission's Joint Research Centre (JRC) has demonstrated biochar's significant potential in both carbon sequestration and soil health improvement.

Research

Role of biochar in carbon sequestration

Biochar in soil sequesters carbon and mitigates greenhouse gases, aiding climate change mitigation.

Biochar as a viable carbon sequestration option

Biochar production and soil mixing offer carbon sequestration benefits; biomass and soil availability support viability.

Project Certifications and Claims

Isometric

This project has passed the Isometric Standard, verifying that its carbon credits are durable, additional, and measured using advanced scientific techniques.

AI Quality Framework

Senken follows a 500+ datapoint AI Quality Framework to select and onboard project developers. Only 5% of the projects we assess score high enough to make it into customer portfolios.

Socioeconomic Impact

Graphyte’s Carbon Casting technology creates new economic opportunities by turning agricultural and forestry by-products into a valuable climate solution. By sourcing biomass locally, the project supports rural economies, provides steady demand for farmers and land managers, and reduces waste disposal costs. Its scalable model fosters green industry growth, generates skilled jobs in carbon removal, and drives investment into sustainable land use practices that benefit both communities and the climate.

Environmental Impact

Graphyte’s Carbon Casting technology delivers long-term climate benefits by permanently storing CO2 captured from biomass in stable, inert carbon blocks. This process prevents carbon from re-entering the atmosphere, reduces methane emissions from decomposing organic matter, and avoids land degradation linked to waste disposal. By repurposing agricultural and forestry residues, the project promotes circular resource use, supports healthier ecosystems, and contributes to global climate change mitigation.

12. Responsible Consumption and Production

Senken's Take

Graphyte’s Loblolly Project exemplifies practical, high-integrity carbon dioxide removal through its unique Carbon Casting process. By transforming agricultural and timber residues into durable, polymer-sealed biomass blocks, it locks away CO2 underground for over a millennium at a fraction of the energy cost of conventional methods. Recognized with an “AA” BeZero carbon rating, it ranks in the top 2% of projects for additionality, permanence, and accounting rigor.

Launched in Pine Bluff, Arkansas, the Loblolly facility has already generated local economic benefits—creating jobs, partnering with the university, and contributing to community infrastructure such as a new park. Backed by leading investors and designed for rapid scale-up, Loblolly sets a high standard for affordable, transparent, and community-resilient carbon removal. As its credits enter the market through Isometric, it stands out as a compelling choice for climate-focused buyers seeking verifiable and durable nature-based solutions.
